Description
본 발명은 높은 단열성과 기공율, 발수성, 초경량성을 가지는 에어로 겔 파우더를 포함하는 초단열 경량 섬유코팅 가공기술에 관한 것이다. 섬유 코팅 가공이라 함은 직·편물 및 부직포 등을 기본적으로 하여 그 표면에 고분자 물질을 균일하게 도포하여 건조, 경화시키는 것으로 의류용, 산업용, 생활용 등에 다양하게 사용되고 있다. 본 발명은 이러한 섬유코팅 가공에 있어서 에어로 겔이 가지는 높은 단열성과 공극율, 발수성, 초경량성을 이용하기 위하여 에어로 겔 파우더를 고분자 물질에 균일하게 혼입, 분산하여 코팅 된 섬유가 초단열, 경량성을 가지도록 하는 것이다.
The present invention relates to a super-insulation lightweight fiber coating processing technology comprising aerogel powder having high insulation and porosity, water repellency, and ultra-lightness. Textile coating processing is based on woven fabrics, knitted fabrics and nonwoven fabrics, and the polymer coating is uniformly applied to the surface of the fabric to be dried and cured. In the present invention, in order to use the high thermal insulation, porosity, water repellency, and ultra-lightness of the aerogel in the fiber coating process, the aerogel powder is uniformly mixed and dispersed in the polymer material, and the coated fiber has a super insulation and light weight. It is to be.
에어로 겔은 우수한 단열성 이외에 기공도가 85%~99%이며, 밀도가 0.003g/cm3정도의 초경량으로 기존 단열재에 비하여 단열성이 3배 이상 우수하다. 일부 극한환경용 의류제품 및 우주복 소재로 사용이 되고 있으나 국내에서는 의류제품 적용에 대한 연구개발이 매우 미비하다. 실리카 에어로 겔 파우더의 경우 0.02W/m·K 정도의 낮은 열전도율로 초단열 특성을 가지며, 0.05g/㎠의 낮은 밀도와 90% 이상의 공극율로 초경량성을 갖는다.In addition to excellent thermal insulation, aerogels have a porosity of 85% to 99%, and have an ultra-light density of 0.003g / cm 3, which is more than three times better than conventional insulation materials. Although it is used as a material for some extreme environmental clothing products and space suits, research and development on the application of clothing products is very poor in Korea. In the case of silica aerogel powder, it has ultra-thermal insulation with a low thermal conductivity of 0.02W / m · K, and has ultra-lightness with a low density of 0.05g / cm 2 and a porosity of 90% or more.
에어로 겔이 가지는 나노 다공성구조로 인한 초단열성의 특성을 이용하여 에너지절약을 위한 단열재 개발에 대한 노력이 전 세계적으로 이루어지고 있다. 미국에서는 NASA 등을 중심으로 에어로 겔 소재를 이용한 항공우주산업용 소재를 개발하고 있다. 상기 초단열 성능을 가지고 있는 에어로 겔 소재를 건축용 단열재, 냉장ㆍ냉동 분야, 산업용 단열재, 일상 생활필수품용 보온 단열재로만 사용할 뿐, 단열, 보온기능 향상을 위한 의류 제품으로의 응용은 미흡한 실정이다.
Efforts are being made worldwide to develop thermal insulation materials for energy conservation using the properties of ultra-thermal insulation due to the nanoporous structure of aerogels. In the United States, we are developing materials for the aerospace industry using aerogel materials, mainly from NASA. The use of the aerogel material having the super-insulation performance as only a thermal insulation for building insulation, refrigeration and refrigeration, industrial insulation, daily necessities of life, application to clothing products to improve the insulation, thermal insulation function is insufficient.
본 발명은 통상의 섬유 코팅용 고분자 물질에 에어로 겔 파우더를 직접 균일하게 혼입·분산하거나 또는 고분자 물질의 점도 조절용 희석제에 에어로 겔 파우더를 혼입·분산한 후, 이를 고분자 물질과 균일 혼합함으로써 에어로 겔을 포함하는 섬유코팅용 고분자 물질을 제조하고, 이를 일반적인 섬유 코팅용 장치를 이용하여 통상의 코팅방법으로 섬유상에 균일하게 도포, 큐어링, 건조함으로써 코팅된 섬유가 에어로 겔의 특성으로 인해 단열성, 경량성, 통기성을 가지는 단열 및 보온성, 경량성이 우수한 섬유 코팅용 가공기술을 제공하고자 한다.
The present invention mixes and disperses aerogel powder directly and uniformly into a polymer material for fiber coating, or after mixing and dispersing aerogel powder into a diluent for controlling viscosity of polymer material, and then uniformly mixing the aerogel powder with the polymer material. A fiber coating polymer is prepared, and the coated fiber is uniformly coated, cured, and dried on a fiber by a general coating method using a general fiber coating apparatus, and thus the coated fiber is insulated and lightweight due to the characteristics of the aerogel. It is intended to provide a fiber coating processing technology excellent in insulation, heat insulation, and lightweight having breathability.
상기한 과제를 해결하기 위하여, 본 발명의 적절한 실시 형태에 따르면, 섬유포지에 섬유 코팅용 고분자 화합물을 코팅하는 섬유의 코팅방법에 있어서, 에어로 겔을 포함하는 섬유 코팅용 고분자 화합물을 섬유포지에 코팅하는 섬유의 코팅 방법을 제공한다.In order to solve the above problems, according to a preferred embodiment of the present invention, in the coating method of the fiber to coat the fiber coating polymer compound on the fiber cloth, the fiber coating polymer compound containing aerogel is coated on the fiber cloth It provides a coating method of the fiber.
본 발명의 다른 적절한 실시 형태에 따르면, 상기 섬유 코팅용 고분자물질은 폴리우레탄, 실리콘, 아크릴, 폴리비닐클로라이드 또는 폴리테트라플루오르에틸렌에서 선택된 1종 또는 2종 이상인 것이 바람직하다.According to another suitable embodiment of the present invention, the polymeric coating material is preferably one or two or more selected from polyurethane, silicone, acrylic, polyvinyl chloride or polytetrafluoroethylene.
본 발명의 또 다른 적절한 실시 형태에 따르면, 상기 코팅방법은 다이렉트 코팅방법 또는 트랜스퍼 코팅방법에서 선택된 하나의 방법인 것이 바람직하다.According to another suitable embodiment of the present invention, the coating method is preferably one method selected from the direct coating method or the transfer coating method.
본 발명의 또 다른 적절한 실시 형태에 따르면, 섬유 코팅용 고분자 화합물 100중량부 대비 0.1 내지 20중량부의 에어로겔을 함유하는 섬유 코팅용 고분자 조성물을 제공한다.
According to another suitable embodiment of the present invention, there is provided a polymer coating composition for the fiber containing 0.1 to 20 parts by weight of an airgel relative to 100 parts by weight of the polymer compound for fiber coating.
본 발명에 의해 에어로 겔이 코팅된 섬유는 우수한 단열성, 경량성, 통기성을 갖는다. 또한, 본 발명의 방법으로 섬유 코팅용 고분자 물질에 에어로 겔을 혼입, 분산할 때 에어로 겔이 가지는 저밀도, 다공성 구조로 인해 균일하게 분산될 뿐만 아니라, 분산된 후에는 장기간 방치하여도 침전되거나, 상이 분리되지 않는다.
The aerogel coated fibers according to the present invention have excellent heat insulation, light weight and breathability. In addition, due to the low density and porous structure of the aerogel when incorporating and dispersing the aerogel into the fiber coating polymer material by the method of the present invention, the aerogel is uniformly dispersed, and after being dispersed, is precipitated or dissipated even if left for a long time. It is not separated.
본 발명에서 사용되는 에어로 겔 분말은 이 기술분야에 일반적으로 알려져 있는 졸-겔 공법으로 제조되는 통상의 어떠한 에어로 겔 분말이 사용될 수 있다. 본 발명에서 바람직하게는 입자크기가 0.1~1,000㎛인 에어로 겔 분말이 사용될 수 있다. 에어로 겔의 입자크기가 0.1㎛보다 작으면 너무 가벼워 비산 문제로 인하여 고분자 물질에 균일하게 혼입하기가 어렵고, 입자크기가 1,000㎛를 초과하는 경우에는 입자가 너무 커서 섬유 표면위에 얇은 막을 형성하는 코팅의 경우 표면이 거칠게 되거나, 입자 탈락의 문제로 인해 바람직하지 않다. As the aerogel powder used in the present invention, any conventional aerogel powder prepared by the sol-gel method generally known in the art may be used. In the present invention, an aerogel powder having a particle size of preferably 0.1 to 1,000 μm may be used. If the particle size of the aerogel is less than 0.1 μm, it is too light to be uniformly incorporated into the polymer material due to scattering problems. If the particle size exceeds 1,000 μm, the particles are too large to form a thin film on the fiber surface. This is undesirable due to the roughness of the surface or the problem of particle dropout.
본 발명의 에어로 겔을 포함하는 섬유 코팅용 고분자 물질로는 이 기술이 속한 분야에서 통상의 지식을 가진 자가 일반적으로 배합하여 사용할 수 있는 모든 종류의 섬유 코팅용 고분자 물질이 사용 가능하다. As the polymer material for fiber coating including the aerogel of the present invention, any kind of fiber coating polymer material that can be used by those skilled in the art generally can be used.
본 발명에 바람직한 섬유 코팅용 고분자 물질의 예로서는 폴리우레탄, 실리콘, 아크릴, 폴리비닐클로라이드, 폴리테트라플루오르에틸렌 등이 있다. 또한 이들 고분자 물질의 점도 조절용 희석제의 예로는 메틸에틸케톤, 톨루엔, 디메틸포름아마이드, 알코올류 등의 통상적인 용제를 들 수 있다. Examples of the polymeric coating material preferred for the present invention include polyurethane, silicone, acrylic, polyvinylchloride, polytetrafluoroethylene and the like. Moreover, as an example of the diluent for viscosity adjustment of these high molecular materials, conventional solvents, such as methyl ethyl ketone, toluene, dimethylformamide, and alcohols, are mentioned.
본 발명의 섬유 코팅용 에어로 겔 함유 고분자 조성물은 고분자 물질 100중량부에 대하여 점도 조절용 희석제는 0내지 99중량부, 에어로 겔 분말은 0.1내지 20중량부를 포함할 수 있다. 섬유 코팅용 고분자 물질은 사용하는 고분자 물질에 따라서 점도 조절제를 사용하지 않고도 사용할 수 있고, 99중량부를 사용하여 적정 점도로 희석하여 사용할 수 있다. 에어로 겔 분말은 고분자 물질의 점도가 낮을 경우 바로 혼입·분산하여 사용할 수 있으며, 점도가 높을 경우에는 점도 조절용 희석제에 고르게 혼입·분산한 후, 이를 고분자 물질과 혼합, 배합하여 사용할 수 있다. The aerogel-containing polymer composition for fiber coating of the present invention may include 0 to 99 parts by weight of the diluent for viscosity adjustment and 0.1 to 20 parts by weight of the aerogel powder based on 100 parts by weight of the polymer material. The polymeric coating material may be used without using a viscosity modifier according to the polymeric material to be used, and may be diluted to an appropriate viscosity using 99 parts by weight. When the viscosity of the high molecular material is low, the aerogel powder may be mixed and used immediately, and when the viscosity is high, the aerogel powder may be mixed and dispersed evenly in a diluent for viscosity adjustment, and then mixed and blended with the high molecular material.
본 발명에서 에어로 겔을 혼입할 고분자 물질의 점도가 70,000cPs 이하면 고분자 물질에 바로 혼입·분산이 가능하고, 70,000cPs를 초과하게 되면 에어로 겔을 적정 점도 조절용 희석용제에 혼입·분산하여 사용할 수 있다. 에어로 겔 분말이 0.1중량부 미만이면 에어로 겔이 가지는 단열, 경량성의 특성을 코팅된 섬유에서 기대하기 어렵고, 20중량부를 초과하면 에어로 겔 분말의 함량이 과다하게 많아지게 되어 고르게 분산시키기 어렵고, 고분자 물질의 코팅 특성에 바람직하지 않다.In the present invention, when the viscosity of the polymer material to be mixed with the aerogel is 70,000 cPs or less, it is possible to directly mix and disperse the polymer material, and when the viscosity exceeds 70,000 cPs, the aerogel can be mixed and dispersed into a diluent for adjusting the appropriate viscosity. . If the aerogel powder is less than 0.1 part by weight, it is difficult to expect the adiabatic and lightweight properties of the aerogel in the coated fiber. If the aerogel powder is more than 20 parts by weight, the content of the aerogel powder is excessively high, making it difficult to disperse evenly. It is not desirable for its coating properties.
본 발명은 에어로 겔 분말이 포함된 섬유 코팅용 고분자 물질을 사용하여 섬유에 코팅함에 있어서, 이 기술분야에서 일반적으로 사용하는 섬유용 코팅방법으로 에어로 겔이 포함된 고분자 물질을 섬유 상에 균일하게 도포, 큐어링, 건조함으로써 코팅된 섬유가 단열성, 경량성, 통기성을 가지도록 하는 것이 특징이다.In the present invention, in coating a fiber using a fiber coating polymer material containing aerogel powder, a fiber coating method commonly used in the art is uniformly applying a polymer material including an aerogel onto a fiber. Curing, drying, the coated fibers are characterized by having heat insulation, light weight, breathability.
본 발명의 에어로 겔이 포함된 고분자 물질의 코팅방법에 있어서 나이프, 키스 롤러, 그라비어 롤러, 블레이드, 패딩 망글 등 통상의 섬유 코팅용 장치를 이용한 다이렉트 코팅방법과 에어로 겔이 포함된 고분자 물질을 필름 또는 시트 형태로 만들어서 섬유와 라미네이션 하는 등의 트랜스퍼 코팅방법 등이 사용될 수 있다.
In the coating method of the polymer material containing the aerogel of the present invention, a direct coating method using a conventional fiber coating apparatus such as a knife, a kiss roller, a gravure roller, a blade, a padding mangle, and a polymer material containing an aerogel or a film A transfer coating method such as laminating fibers with a sheet may be used.
